Title: Hot water supplying apparatus for bath
Inventor: FUJISHITA KAZUO
IPC: F24H1/00
Filed: 1984-03-27
Abstract: PURPOSE:To make it possible to supply hot water into a bathtub in a state where a lid is closed thereby to realize an energy-saving hot water supply by enabling introduction of hot water having a suitable temperature obtained in an instantaneous water heater through a circulation heating circuit of the bath. CONSTITUTION:The tip end of a hot water supply pipe 19 is commanicated with the downstream side of a check valve 20. Further, a water quantity sensor 21 is provided between a switching valve 16 and a vacuum break valve 17. A return pipe 15 and an outgoing pipe 11 from a circuit for circulation and have each a diameter smaller than the diameter of a hot water feed pipe 6a. Further, the composite type hot water feeder is installed at a position which is higher than that of the bathtub 12. Since the check valve 20 is provided in the circulation circuit, hot water is prevented from being introduced to the heat exchanger side of the bath furnace at the time of a hot water supply and also from radiation loss. Further, by closing the switching valve 16 air is taken in through the vacuum break valve 17 and is mixed into the hot water feed pipe, whereby hot water within the bathtub is prevented from counterflowing to the side of the instantaneous water heater 1.

Title: Magnetic disc unit
IPC: G11B21/21
Filed: 1992-03-17
Abstract: PURPOSE:To enhance impact resistance by retreating a slider to an outer radial region of a magnetic disc when a magnetic disc unit is not working. CONSTITUTION:Upon turn OFF of power of a magnetic disc unit, an arm 7 moves to the outer peripheral side of a magnetic disc 4 and thereby a suspension 1 and a slider 3 supported at the tip of the arm 7 also move to the outer peripheral side of the magnetic disc 4. Since the magnetic disc 4 is rotating, at that time, at a speed defined by the inertia the slider 3 moves while floating. The floating operation is stabilized through balance of force and thereby the slider 3 does not contact with the surface of magnetic disc nor vibrate during movement.

Inventor: NOOMAN ROJIYAA RANPAATO
IPC: G02B6/38
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To provide an optical connector including an immobile ferrule. SOLUTION: This connector 10 is cast to a shape integral with a housing. A latch 120 exists in a socket 50 in order to hold the housing. This latch 120 is a cantilever and its stationary end faces the front surface end of the housing. The housing has a hole in an axial direction and an optical fiber is inserted therein. The passage is formed to a length about half the length of the housing facing to front surface end from the rear surface end of the housing along the longitudinal direction of the housing. This connector 10 further includes the ferrule 140-2 fixed to the housing and faces the front surface end of the housing along the longitudinal direction of the housing from the middle point of the housing. The ferrule 140-2 has the passage in the axial direction where the end of the optical fiber 30 is received.  The hole and the passage are arranged in the housing in such a manner that both are aligned and are brought into contact with each other. Since the ferrule 140-2 is fixed to the housing, the need for a base member and spring is eliminated.

Title: Depth measurement method for hardening cured layer
Inventor: SAKANO AKIRA
IPC: G01N29/09
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To measure the depth of a hardening cured layer even if a work surface has a small curvature, by using a correction member comprising a mating surface possible to be tightly contacted to the work surface and a flat correction surface. SOLUTION: A correction member 3 comprises a mating surface 3a possible to be tightly contacted to the surface of a switching part 91 of a work and a flat correction surface 3b facing the mating surface 3a with a predetermined thickness t. The mating surface 3a of the correction member 3 is tightly contacted to the surface of the switching part 91, and, through the correction member 3, transmission and reception of ultra sonics is perforated by a high frequency probe 2. Thus, based on the difference between the propagation time of correction reflection wave and that of border reflection wave, depth L of a hardening cured layer W1 from the correction surface 3b is obtained. Then, by subtracting the thickness t of the correction member 3 from the depth L, depth x from the surface of the hardening cured layer W1 is obtained.  Therefor, even at the surface of the switching part 91 with a recess R, the depth x of the hardening cured layer W1 is measured.

Title: Air conditioning facility
Inventor: FUKUSHI YUTAKA
IPC: F24F11/04
Filed: 1993-03-19
Abstract: PURPOSE:To perform stable airflow control, which follows a great change in airflow and is free of abnormal noises, resonance and the like, by applying floating control, which is consisted of step control step by step, to a control output of an air conditioning facility provided with variable airflow ventilators when air is fed to a plurality of air conditioning zones. CONSTITUTION:When YES results from judging whether a demanded airflow varies greatly or not, it is meant that there is not so much change in airflow, and so control shifts to floating control. Also, whether at least one variable airflow ventilator (VAV) is fully opened or not is judged, and whether demanded airflows of one or more VAV are greater than a detected airflow or not is judged. Furthermore, whether demanded airflows of one or more VAV are equal to a detected airflow or not is judged. Then whether a one step-up output is in a jumping region or not is judged. In this manner, stable airflow control is performed corresponding to a great change in airflow.

IPC: B65H7/18
Filed: 1979-05-17
Abstract: PURPOSE: To make the matching of the leading ends of the original and sheet easy by beforehand feeding out the sheet by the speficied distance thence once stopping the sheet feed means and re-feeding the sheet by the feed start signal associated with the scanning means.  
     CONSTITUTION: A sheet feed roller 1 assumes sectional shape which is partly notched at its circumference. The roller 1 feeds out the sheet 4 1  in the uppermost position up to the position of a register roller 5 in one revolution. Now, when a copy button is pushed, the sheet feed roller 1 is begun to be revolved prior to starting of the original scanning and is remolved by the specified angle. Just before it lets the sheet 4 1  arrive at the register roller 5, it is stopped and is standing by in that state. After this, the original platen starts original scanning and a timing position is detected by a known detecting means on the way of the movement so that the restarting signal for the feed roller 1 is emitted. The sheet 4 1  is again fed out, whereby the timing with a photosensitive drum 6 is matched.
